How do I interpret the lights on the AyrMesh Receiver?

The lights on the AyrMesh Receiver show that it is working properly and indicate the strength of the signal from the AyrMesh Hub to the Receiver. They are on the back of the receiver, and look like this:

From Left to Right:

First is the power light (green) - this should always be on

Second is the Ethernet activity light (green) - this indicates traffic on the Receiver's Ethernet port - it should be on or blinking if anything is attached to the Receiver's LAN port

Third is the first signal light (red) - if this light is on alone, it indicates poor signal strength from the Hub - less than -75 dBm

Next is the second signal light (yellow) - if only this and the red light are on, it indicates moderate signal strength from the Hub - between -65 and -75 dBm

Next is the third signal light (green) - if this, the yellow, and the red light are on, it indicates good signal strength - between -55 and -65 dBm

Finally, the fourth signal light (green) - if all the signal lights are on, it indicates very strong signal - less than -55 dBm

When the Receiver boots, the rightmost light (green) will blink, and then the four signal lights will "chase" from left to right, indicating that the Receiver is trying to connect to an AyrMesh Hub. When it is connected to the Hub, the signal lights will indicate the signal strength. The signal lights change approximately once per second.
